Problem
Prompt or model changes ship on gut feeling. An improvement in one case breaks others and nobody notices.
Solution
A versioned evaluation set, fed by real traces, runs on every change. Releases happen only if metrics do not regress.
When to use
- →Any AI system in production
- →Teams that change prompts often
- →Model switches or upgrades
## Trade-offs
- +Evidence-based changes
- +Regressions caught before users see them
- −Cost of running evaluations
- −Requires curating the cases
